Re: Dyno chart from a Penske shock ?

Hank,

I'm using a 1000 lb spring on my 8981, and it's about right for my weight of 180 with gear. I wouldn't want to go any lower. I did try a 1200 lb spring, but it was a bit too much spring for the street. I commute and ride in the mountains, not much track work.

Took me a while to get the new scanner working... Attached is the dyno chart from the Penske I got from RodeRash. I can't comment on the performance. Wisconsin winter set in before I got a chance to get it installed... Hope it helps.

Re: Dyno chart from a Penske shock ?

RR, thanks for posting that chart.

Maybe a little background...As you add horsepower to a bike, in larger amounts, the overall package becomes a series of compromises. Big HP is useless if the bike constantly wants to wheelie over backwards. Stretching out the wheelbase is one way to handle this, and lowering the bike is another; but now you have something that hates curves. The suspension comes into play when rolling on the throttle, even in a straight line. Now, hang a turbo off the front of the motor while taking the mufflers off the rear and you've altered the weight bias. Jam an intercooler in front of the radiator and you loose .300"-.400" of wheel travel. Throw in some of the bumpiest roads in the nation as your daily riding invironment.
These are some of the things I threw at NCRick to help solve, and finally:
"And Rick...by the way...keep the price down."...LOL
Anyhow, he thought it would help to see a dyno chart from a known good shock, dyno a stock shock, and then disassemble it to see if he could work some magic internally or if it was beyond help. The front allows for some interesting options, some kinda inexpensive and some natso. Thats where I'm at today and why NCRick kindly got involved with this thread . The forks are all apart at his place and he's waiting for a rear shock to disassemble..Stay tuned...Hank
